Summary: header changes to allow PocketPC development

Initial Comment:
The included patch makes changes to four existing files in
src/winsup/w32api/include/, and adds a new file.  The
purpose of my
changes is to allow PocketPC applications to be
developed using the
same set of headers as are used for win32 apps.

My changes are of three types.  The first modifies
structs (one struct,
WIN32_FIND_DATA, with A and W variants) to remove and
rename fields
to align it with the definition in the documentation on
MSDN.

The second changes the declarations of functions not
found in DLLs on
PocketPC.  Rather than remove them altogether, I've
conditionally
declared them 'extern' as an indicator to developers
that they will
need to provide their own implementations.  Over time I
hope to add
implementations to the pocketpc development suite in
Debian.

The third change adds new functions and struct
declarations that are
used only for PocketPC development.  As before, I've
taken the
definitions from the documentation on the MSDN site. 
And again, some
functions that appear not to be in the DLLs are
declared extern, when
I couldn't figure out from the MSDN docs how to
implement them inline,
or provided as macros.

The sources of information are MSDN API docs and an
obscure article
that happens to give the ordinals for two functions
that are not
exported by name:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncenet/html/wincenet_cepcc_app.asp

I've used two methods to test my changes.  First, I've
compiled and
run a large open source app (xwords.sf.net) against the
MinGW headers
with my changes in place.  In most cases my changes
have fixed bugs in
the app.  For example, the change to WIN32_FIND_DATA
stopped the
cFileName field from losing its first two bytes. 
Second, in cases
where I did not use an API I was adding I wrote a
trivial test app and
verified that it would load correctly on the device.

These changes are not fully useful without
corresponding changes to
the pocketpc-sdk package on Debian.  For example, the
code at
xwords.sf.net will not link without them.  I am
submitting patches to
that package as well.
